Lubrication of hot-strip-mill rolls - ScienceDirect

1973-2-1 · LUBRICATION OF HOT-STRIP-MILL ROLLS 205 To avoid problems with front-end entry the oil was switched on by a signal from the main-drive motor load and switched off before the tail end had passed through the mill by similar means. In this way time was allowed for the oil to "burn on" the rolls before the next slab was ready for processing.
